摘　　要：详细介绍了因氮气流量计工作压力下降、指示偏低 ,实际氮气流量偏大而引起主塔精馏工况异常 ,造成粗氩塔氮塞的故障现象及防范措施。The abnormal conditions of the distillation column occur due to the drop of operating pressure in the nitrogen flowmeter,the low side indication and the high side indication of actual nitrogen flow are described in detail,which result in blockage of crude argon column by nitrogen.Correspondingly precautions are set forth for reference.
